You will need to go with at least a 7CF freezer to fit in 4 cornies (pin or ball). I have ball locks because I bought those first.

Four ball lock kegs fit in my 7.5' Lowes special snugly.

Pin lock kegs are slightly shorter and have a bit wider circumference. I am not 100% sure that 4 would fit in my freezer but every model is a little different.

Both kinds will do the same job but I think it helps to standardize on one type to save work and expenses.

Would you be able to give me your inside dimensions of your freezer? I went to home depot the other day and I don't think their 7.5CF freezer will work.

I got my freezer at Lowes a few years back. Not at home right now so I can measure it. I made keg templates (fancy name for circle cut out of card board) to make sure 4 of my kegs would fit. My unit only has the back right corner bumped out, not a whole shelf. If there where a whole shelf 4 kegs would not fit.

Sweet! I appreciate it. That's a good idea to take 4 templates. Yeah, the one at home depot has an entire shelf. So it really only has about 15" X 23" to work with. I was running about 5 inches short on the length. If the compressor box is just one corner, it would definitely work.
